IMPROVEMENT IN COOKING-STOVES.

Specification formingvpart of Letters Patent No. 110.230, dated December20, 1870.

To all whom it may confiera:

Be it known that I, WILLIAM HAILES, of the city and county of Albany andState of New York, have invented a new and Improved Boiler Attachmentfor Cookin g-Stoves; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing, making part of this specification, in which-Figure l, Plate 1, is a sectional view of a cookstove, showing theimproved boiler attachment. Fig. 2, Plate 1, is a top view of the stoveandv boiler attachment of Fig. l. Fig. 3, Plate 1, is a front view of aboiler detached from a stove. Fig. 4, Plate 2, is a section takenvertically through the boiler. Figs. 5 and 6 show a modication of theattachment.

Similar letters of reference indicate correspondin g parts in theseveral figures.

This invention relates to certain improve` ments on the construction ofboiler attachments to cook-stoves, wherein the products of combustionpass off through the boiler, whether there be a direct or indirectdraft.

The nature of myinvention and improvements consists, first, in areservoir for cookstoves, wherein a smoke-flue passes vertically throughit, one wall or side of which constitutes one of the walls of thereservoir, in combination with a concave bracket or shelf, which isformed on the back wall of the stove, and

which constitutes the entire horizontal outletflue of the stove, as willbe hereinafter explained; second, in a rim or upper flange,

which is cast separate from the reservoir, and adapted to serve as ameans for attaching the reservoir to the stove at its upper end, andalso as a skirting for retaining heat about the upper wall of thereservoir, as will be hereiny after explained 5 third, in constructingthe bridge or fixed cover of the reservoir with oblique edges, to whichthe principal covers are hinged, whereby nearly the entire supercialarea of the top of the reservoir can be exposed, to allow free access tothe interior thereof, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I willexplain its construction aud operation.

vIn the accompanying drawing, Figs. 1 and 2, A represents a well-knownform of singleoven cook stove, having a central Hue, a, arranged betweenthe two side flues b b, and with a damper, D, which, when shut, willcause the products to take an indirect course through the due-spaces ofthe stove before passing off. When damper D is open the products takethe shortest course to the exit-passage.

Through the back wall of this stove is an exit-Hue, G, which is incommon with the direct and in direct draft, and which is arranged belowthe level of that portion of the iue a which is between the top plate ofthe oven and the top plate ofthe body of the stove. Beneath this openingG, and external to the stove, is a concave bracket or shelf, B, which isintended as a support for a water-reservoir, C, and also as an externalcommunication between the ue a of the stove and a vertical iiue, c,which passes up through the body of said reservoir C. The reservoir C isadapted to fit snugly against the back wall of the stove, and to restupon the bracket or shelf B, to which it is fitted by means of a flange,p, cast on the bottom of the reservoir.

Through the body of the reservoir passes a Hue, c, which forms acommunication between the exit-opening Gr of the stove and thechimney-iiue. This iiue c is an integral part of the reservoir, and isconstructed with it in such manner that part of this flue forms part ofthat wall of the reservoir which impinges against the back plate of' thestove; or, as in Fig. 5, hereinafter to be described, the back plate ofthe stove forms part of the wall of the ilue c.

The objects of thus constructing the iiue c will be hereinafterexplained.

Surrounding the upper edge of the reservoir is a flange, rim, or skirting, d, the front portion of which rests upon the top plate of the stove,and is connected thereto by studs e, which are cast on the ilange d, andwhich extend down from offsets f and enter holes made through the saidtop plate. In this manner the reservoir is secured to the stove abovethe bracket or shelf B without the aid of nuts and bolts.

The rim d forms a skirting for the top of the boiler, and extends belowthe upper edge thereof; and with this rim or skirting is cast a bridge,g', which tapers backward, and

which has an opening through it, surrounded by a pipe-collar, to receivethe stove-pipe flue c, so as to preserve the continuity of flue. Thebridge-wall g is tapered backward, and has hinged to it the covers g g,which are at their hinged edges also beveled, as shown in Fig. 2. Bythis means nearly the entire area of the top opening of the boiler willbe exposed when the covers g g are raised, thereby affording betteraccess to the interior of the reservoir than is afforded where thehinges and the edges of the top bridges of reservoirs are parallel or inline with the length ofthe stoves.

In Figs. 5 and 6 the front -portion of the iiue c is open from its lowerend to a point which is on a level with the top plate of the stove, andthis lue receives the wings or beveled ribs m m, which are cast orotherwise applied to the back wall ofthe stove. This formsa kind ofdovetail attachment of the reservoir to the stove above thesupporting-bracket or ueshelf B, and is considered the equivalent of theattachment first described.

In the boiler attachment to a cooking-stove which was patented to GeorgeH. Phillips on the 2d day of February, 1869, a depressed boiler isshown, which is supported upon a concave bracket at its base, and whichis attached above to the top plate of the stove by means ofscrew-fastenings. In this boiler attachment the ue which passes throughthe boiler is isolated from the side walls thereof, and passes throughthe central bridge of the boiler. The lower end of said iiue also formspart of the horizontal flue leading from the main iiue of the stove.

I do not claim as my invention anything which is shown in the patent ofPhillips above referred to. I do not claim a depressed boilerattachment, nor a ue passing through a boiler which is applied to theback of a cook-stove; nor do I claim a concave shelf on which to supporta boiler at the back of a cook-stove.

I have constructed a boiler for a cook-stove having a concave shelf, B,which has a ue passing through the boiler, one part of the wall of whichflue is in direct contact with or forms part of the flue of the stove,by which means the boiler can be practically made and furnished to themarket at a reasonable cost.

I construct the top of the boiler separate from the body thereof, and insuch manner as to forni a skirting, which extends downward and outward,and serves to support the body of the boiler upon the top plate of thestove, to afford a firm and substantial attachment of the boiler to thestove, and also to arrest the heat rising from the boiler externally.This rim, flange, or skirting is constructed with the tapered bridge g',and also with the pipe-collar, to receive the upper end of iiue o andthe external stove-pipe.

I desire to be understood by the words depressed reservoir 7 a reservoirwhich is wholly or partially arranged below the top plate of the stove.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. The depressed water-reservoir C, having a vertical tlue arranged indirect relation to the back wall of the stove, and with the concaveshelf B, in combination with the rim or skirting d and studs f,substantially as described.

2. The rim d, made of one piece in the forrn of a skirting, with abridge, g', and with pipecollar, in combination with a depressedreservoir, C, and vertical tlue c, as shown and described.

3. The bridge g of flange d, when it is tapei-ed on opposite sides ofits pipe-collar, as described, for the purpose set forth.

VILLIAM HAILES.
